AHT Error message - 4MOT/4/40000003: HDD - 1248

Hi folks........ i'm looking for some help on a AHT error message?
The error message is 4MOT /4/40000003: HDD - 1248
Has anyone any ideas what this is?
Thanks
Paul

You're looking at a drive issue, possibly heat and or fan related. Google is pretty good at pulling up posts for the error message.
If the system is still working and the drive is accessible make sure you do a backup right way and then make an appointment with Apple.
good luck
regards

Error message 4MOT/4/40000003:HDD-1278.

After hardware test, my iMac is showing error message 4MOT/4/40000003:HDD-1278 Should I be concerned? Best, Paolo

Yes Paolo, you should be concerned. That error code indicates the fan that cools the hard drive has failed or is failing. You'll likely need professional help to overcome this.

I believe you've posted this multiple times. Once is all that's needed. Also, please don't use all caps. Aside from the fact it means you're shouting it's also harder to read than mixed case.
The error means a bad fan motor or the HDD has failed. In your case it's the latter. You can try the following:
Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
When formatting has completed quit DU and return to the installer. Complete the OS X installation.

I ran a apple test and got a error code 4mot/1/40000003:hdd-1376 does anyone know what this is thanks

Buy a new drive and replace the old one. While the old one is still working (if it is) I would quickly make a bootable backup to an external drive if you have one, assuming you have no extant backup.
Clone using Restore Option of Disk Utility
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
You will find suitable replacement drives at OWC.
They may also have a video tutorial. Or you may find a written tutorial at ifixit.com. Also may find one by Googling for it.

Alternatively, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

Error code - 4MOT/4/40000003.HDD

Can anybody please give me some advice on what the above mentioned error code is as my iMac is failing to do anything except start up,
Thanks Mark.

Hi,
Try these below in order, to check whether you can boot the machine further:
Intel-based Macs: Resetting the System Management Controller (SMC)
About NVRAM and PRAM
OS X: About OS X Recovery to confirm that the internal disk is accessible.
Afterwards, try a normal reboot.
If the machine is still not booting:
Refer: Hardware Test 4MOT/4/40000003: HDD-1326
and Using Apple Hardware Test
Cheers

I run a hardware test and it gave me the error code 4mot/4/40000003:HDD-1500: does anyone know what it means?

Hello,
I have a problem of my iMac freezing up regularly for no obvious reason.
So I ran a hardware test and it returns me only with the code 4MOT/4/40000003:HDD-1500.
I need some help to know what that means and how to repair my iMac.
William

William, unfortunately it means your hard disk drive has or is failing and needs to be replaced. Hopefully you have a current backup or clone. You can have the drive replaced at an Apple Store or AASP or do it yourself if you're inclined by following the guide fir your specific iMac at http://www.ifixit.com/Device/Mac_Desktop

Error Code 4MOT/1/40000003:HDD-1344. I got this code after running hardware testing, does anyone know what this means? Thanks

Anyone heard or seen an apple hardware error code 4MOT/4/40000003:HDD-1255 ?

i just did an apple hardware test and this is what i got. my imac running slow. it hangs and stutters often.

It may mean the hard drive is failing or has failed but try den.thed's suggestions here > https://discussions.apple.com/thread/2466535?start=0&tstart=0

After installing a new hard drive the fan is very noisy. Hardware test error code 4MOT/1/40000003: HDD-1417

I've carried out all the trouble shooting procedures.The fan is running @ 3899rpm and the temp is 26 deg celsius. (I'm assuming the sensor is working OK...it may not be) A SMART test was OK, can anyone please identify the code and suggest a solution.
Thanks
roger190

There are temperature sensor on the Apple installed hard drives. Did you reattach this to the new drive? If so how well / badly was it stuck on? Was the sensor damaged during the install of the new drive?
The fact the fans are running @3899rpm shows something is not quite right.
Is it possible the new drive is faulty? See here:

AHT erreur 4MOT/4/40000003:HDD-1289

bonjour,
je possede un imac 27" mi-2010 core i3
lors du test avec apple hardware test, j'ai une erreur 4MOT/4/40000003:HDD-1289
quelqu'un a til une idee sur la cause de l'erreur.
a savoir egalement que mon imac a eu il y a 2 ans le hdd changé suite a une campagne de rappel.
dans l'attente de vos reponses
salutations

From the results of a few searches online, the AHT error appears to mean this:
4MOT (motor) & some suggest that would be a fan issue, perhaps cooling HDD.
However there may be more than one thing going on in the computer and you
may see if an Apple Store with Genius bar could help diagnose similar results
and give you their take on the meaning of these codes. Appointments usually
are necessary, and even if the computer no longer has Applecare coverage,
you usually can get some help and an idea what's going on. If no Apple Store
(with genius bar) you may need to try an Apple Authorized Service Provider.
Or check around for an Apple Specialist. You'd likely pay for diagnostics, then.
Sometimes if there's excessive dust in the computer, it may show things are
acting up, such as overheating; or fan failure, cooling issues, etc. Or a hard
disk drive that may be running hot or on its last legs & needing replaced.
The error indicates a hardware cause, so this may be a symptom of pending failure.
But the temperature sensors may be acting up, if this relates, and the margin of
error for them may be compromised if there is dust inside affecting cooling efficiency.
Without knowing for sure, the exact build model iMac, can't say if there may be
another issue going on to contribute to the Error message. Or if there had been
a EFI firmware update for that computer, still in existence, that may apply. Given
the age and wear, an earlier iMac may need a replacement hard disk drive by now.
In any event...
Good luck & happy computing!

AHT 4MOT/1/40000003:HDD will replacing the fan fix the machine?

My 2007 imac started freezing on me, but a reboot would fix it. Finally, it just froze and when I reboot it takes forever, gives a garbled grey screen and then loads the OS and displays the desktop. Everything seems fine until you click on something. Then everything freezes again (forever).
When I ran AHT, I got the error 4MOT/1/40000003:HDD (with no trailing numbers), which I understand to be a hard drive fan er
I have all of my data backed up to a time machine drive so I'm not worried about my data, but what are the chances of the computer working again if I spend the money to buy a fan and replace it? Thoughts?
Any help will be much appreciated.
It's a 20 inch 2.4 GHz 2007 iMac (2133)
Thanks for your assistance!

That error message indicates a hard drive fan issue. The problem is that you have to replace the whole hard drive, not only the fan.
I recommend you to take the iMac to an Apple Store or reseller to get the hard drive replaced, so you won't have to worry about doing something wrong while installing it, and then, just restore your Time Machine backup. Anyway, if you want to install the hard drive yourself, you can find the steps to do it in OWC or iFixit.

Error: 4MOT/4/40000003-HDD-1355

Please help, I have the following message when running the Apple Hardware Test:
Error 4MOT/4/40000003-HDD-1355 on the quick test,
the extended test was identical except for the last 4 digits which were 1362.
Previous posts seem to indicate it is the fan that cools the hard drive, the last four digits indicating the fan's speed.
Could it be the hard drive or the logic board?
Thanks in advance for your help.

Mike:
First, thanks for helping me. Second, I believe you are right and it is the hard drive. I had a white screen the other day. I shutdown using the power button. Later, more white screens combined with restarts. I downloaded Yosemite and that fixed the problem for about 48 hours. Then white screens again. At one point it was going from a white screen to restart over and over for about 7 minutes until it finally was able to get to the desktop. Sounds like a hard drive towards the end of its useful life. Will know for sure on Tuesday, and will post to let you know. Hope it isn't too expensive a repair. Thanks again, I really appreciate your help.

My Mac is doing strange things: delaying between users, mouse flickering and bouncing, gets stuck with rainbow wheel flickering. I ran the appel hardware test and it detected an error: 4MOT/4/40000003:HDD-1233 Does anybody know what that means? HELP!

My imac is doing strange things:
-delaying between users: when closing session it goes to blue, then takes a while to appear users signin box, and then wont recognize mouse command to enter until a couple of minutes later... then everything seems alright until....
-it gets stuck between things, the rainbow wheel appears and its just delays there forever....
-and every now and then the mouse starts flickering and bouncing wildly onscreen.
I ran the appel hardware test and it detected an error:
4MOT/4/40000003:HDD-1233
Does anybody know what that means? HELP!

WZZZ answered about where to get iStat. And do check the SMART status. If it is an overheating problem due to a fan or logic board problem, your hard drive is possibly cooking itself to death. If so it isn't a faulty hard drive even though the hard drive might fail. So assuming it's a temperature problem, even if you are able to repair things on the disk with software, that is working on symptoms, not causes. I could be wrong however.
RE: AppleCare: Your iMac came with one year of AppleCare (Apple's warranty program), but within the first year you can buy 2 more years. You have to extend by the one year anniversary of purchase of the computer. Your 10,1 is too old to still be in the first year, and since you asked what it was, I'm sure you don't have it. Bottom line meaning is that whatever this problem turns out to be, you'll have to pay for it. Unless there is something like this. It is for 2011 iMacs with certain Seagate drives. You can put in your serial number for fun, but it looks like yours is too old. Lastly, some people have had Apple help them anyway if it is just out of warranty, but many have not. Your machine is one of these. Type in 10,1 in the search box. Is there an Apple Store near you? Just b/c it's out of warranty doesn't mean you shouldn't have it looked at by Apple. But no one here can say at all what Apple will or will not do.
Hope you get it taken care of!

4MOT/1/40000003: HDD-1344 Error, but no problems!

Hi, I got the infamous 4MOT/1/40000003: HDD-1344 error while doing my hardware check, however, I do not seem to have any problems with my mac, the fan speed is around 1300RPM, and 38 celsius. It is not loud, and it is working, and everything seems fine.
I know they say 'if it's not broke, don't fix it', but it is annoying me, and I'd hate anything to mess up...
Google seems to think it is a fan issue, but I really am not having any problems with it, and have not noticed any change.
I recently replaced the stock HD with a Crucial M4 SSD, and have had a few 30-second freezes, but haven't for a while, and have just updated the firmware that is meant to stop it.
If anyone has any idea how to stop this error, it would be greatly appreciated. Preferably something where I do not have to open it up!
Thanks!
Jonny

I wanted to finish the test to see if anything else was up.
I let the computer cool down and left it off for a bit, and the test eventually worked on the quick test, but had the error on the full test, must have heated up too much. But everything seems fine, so problem solved! Thanks!
